Easy 2 -7/16 nuts and the screw on water connection in the back. They are the same between the 300/310 models.

X2 Picked up my replacement toilet (a 310 for the stinky 300) today from my dealer and it installed easily. No need to change the baseplate or the water supply fitting. The hardest part was getting a wrench on the nut just below the pedal, since I couldn't see what I was doing and had to go by feel. The dealer was cooperative and Dometic responded quickly and without any hassle. Glad I could get this all accomplished before leaving for the rally in Goshen.

Here's a question. If you have a 300 and haven't experienced problems but are afraid and don't want to wait until problems develop is there anything you can do to get a 310 replacement or do you have to wait for the dreaded smell?

This is my fifth RV. For the past twenty years I have only rarely used any chemicals. I have never had an odor problem. This odor is very strong. This has nothing to do with how I maintain the system. Something is defective. I do always have water in the black tank.

Speaking of toilets in general. Our Windjammer came with a Thetford toilet (don't recall model). At 4 am one morning my DW woke me up screaming that the toilet broke and she couldn't stop it from flushing. It ended up being the foot flush just fell off the side of the toilet. I have had so many problems with the cheap junk FR uses in these expensive units. I installed a Dometic 310, on my own with no help from FR, Thetford or the dealer, and because of past experience with Dometic products.

FR sells price pointunits and they are not expensive for their size. In most cases the cheap junk is the same from mfg to mfg, and we consumer just lap it up. Not many alternatives out there that are better, that I have seen, at least in the current model years. Some of the stuff in the older models from all mfg's were better like 2008 and before, but those are getting older now.

Dometic did send me 2 toilets and I only had an issue with 1 of the bathrooms. I asked the same question regarding the one bathroom that isn't having an issue and they said they would just send out 2 anyways.

I haven't had issues with the toilet in my Windjammer, but your comments raised my curiosity, so I went out and looked to see which brand I have... turns out my Windjammer has a Dometic 310.

I'm new to Windjammer and Forest River, you mention "many problems with the cheap junk FR uses in these expensive units" so now I'm wondering... what other problems beside toilet I may need to be looking for?

It looks like we did the same job today. All went well with the replacement and I am impressed with Dometic service.

FR may have changed brands of toilets from my 2012 to your 2013...good for you.
Another major issue is the cheap Chinese load range C tires...come on folks lets buy American and use a tire that is adequate to carry the weight of an average loaded trailer. I will be going to a D or E tire before the next lomg trip.
Personal preference...no backup lights! Not so much to light up the area behind the trailer but for SAFETY! Imagine yourself behind a trailer backing up with no way to indicate the trailer is headed towards you. My Artic Fox 29V had backup lights and came in handy many times like when my DW is behind the trailer directing me she can tell at a quick glance if the trailer is coming towards her or not. BTW, we use walkie talkies for that task.
Manufacturers just cutting corners for a few dollars and putting a $36,000 price tag on them.

Does anyone have a contact number for Dometic? I called the number on their website but it directs me to the nearest service center. Should I follow through with that and talk to someone there or is there a better number to call?

Back up lights are an idea........ Never seen a trailer with them but there may be some out there.......might be an idea there I'm thinking of putting a camera back there but too many other projects right now..........
